Abstract： The principle and the system of a ultrasonic liquid level instrument for high pressure container are introduced.The effects of the ultrasonic attenuation of multiple mediums、the temperature、the pressure and the components are discussed,and the resolving methods are proposed.The transducer of the instrument is needed to touch to the bottom surface of containers.So it is very suitable for the measurement of high pressure container liquid level.
